Abstract
En el año 2000, el grupo SIGTRAN definió un nuevo protocolo de capa de transporte conocido como Stream Control Transmission Protocol (SCTP) pensado, inicialmente, para transportar señalización telefónica SS7 sobre IP. La intención fue proveer en IP algunas de las características de confiabilidad de SS7. Por su versatilidad, más tarde, se ha propuesto utilizarlo en otras áreas. Para tal fin, se ha realizado este proyecto fin de carrera, en el cual se estudiarán las características del protocolo y se probarán mediante aplicaciones cliente/servidor desarrolladas en los lenguajes de programación C y Java. Primero, se realizarán pruebas para familiarizar al programador con los distintos APIs (Application Programming Interfaces) de socket SCTP y, finalmente, se plasmarán los conocimientos adquiridos mediante éstas en una aplicación más compleja que permita probar el funcionamiento del protocolo motivo de estudio como capa de transporte en un entorno de transmisión de datos en tiempo real, concretamente streaming de video, dónde se simularán caidas de los interfaces de red. Para realizar esta última parte del proyecto se utilizará Java Media Framework. _________________________________________________
In 2000, the SIGTRAN team defined a new transport layer protocol known as Stream Control Transmission Protocol (SCTP) thought, initially, for transport SS7 telephonic signaling over IP. The intention was to provide some of the reliability features of SS7 to IP. Then, because of its versability, it has been proposed to use in other areas. To that end, this final career project has been realized, in which will study the characteristics of the protocol that will tested by client/server applications developed in programming languages C and Java. First, tests will be conducted to familiarize the developer with various SCTP socket APIs (Application Programming Interfaces) and finally, will translate the knowledge gained through these in a more complex application that allows testing the operation of the protocol under study as a layer transport in an environment of real time data transmission, specifically video streaming, where will simulate crashes of network interfaces. To make this last part of the project will be use Java Media Framework.
